This course covers the Critical Rendering Path (CRP) process from start to finish, where the browser receives HTML to create the DOM, combines it with the CSSOM, and renders pixels on the screen. Beyond simple DOM manipulation, you'll learn how CSS and JS impact performance, image and font optimization, Lazy Loading, Intersection Observer, virtual lists, and DevTools practice, gaining practical strategies to noticeably improve real web performance.

This course goes beyond simple DOM manipulation, deeply learning how to dynamically compose and react to web UIs within interactions with actual users. It's structured for you to learn by directly implementing common issues encountered in practice, from the essence of event systems, bubbling and capturing, event delegation, real-time UX feedback, to performance optimization using throttle & debounce. Based on an understanding of the DOM tree structure, you will develop the ability to flexibly connect event flow and state changes.

This course will help you develop mobile apps that can be serviced on Android and iOS using web development.
